A display system with video see-through eye display unit is disclosed. The eye display unit includes: at least one camera unit; at least one image forming module; and an optical deflection module including at least one double sided light reflecting optical element which is at least partially reflecting to light arriving from both sides thereof. The camera unit is configured for collecting light arriving from a region of interest of a scene along a first optical path intersecting the optical deflection module, and generating image data indicative of the region of interest. The image forming module is configured for receiving imagery data indicative of images to be projected to an eye of a user, and generating and projecting the received images to propagate along a second optical path intersecting the optical deflection module. The double sided light reflecting optical element of the optical deflection module is arranged in the display system to be located in front of the eye while intersecting the first and second optical paths, and is oriented to define the first optical path (between the camera unit and the scene) and the second optical path (between the image forming unit and the eye), such that the camera unit has a point of view substantially similar to line of sight of the eye.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A system, comprising: an eye display unit, comprising: at least one camera unit configured for collecting light arriving along a first optical path from a region of interest of a scene and generating image data indicative thereof; at least one image forming module configured for receiving imagery data and projecting images of said imagery data along a second optical path towards an eye of a user; and an optical deflection module comprising at least one double sided light reflecting optical element being reflecting to light arriving from both sides thereof and having at least one side being 95% or more reflective, the double sided light reflecting optical element being located in front of said eye intersecting said first and second optical paths, and oriented to define said second optical path between the image forming module and the user's eye, and define said first optical path between said at least one camera unit and the scene, such that light propagating along said first optical path from the scene is reflected by said 95% or more reflective side of the double sided light reflecting optical element to said at least one camera unit; thereby providing said at least one camera unit with a point of view substantially similar to line of sight of the user's eye.
2. The system of claim 1 , wherein said at least one camera unit is located along said first optical path at an optical plane corresponding to the optical plane of said user eye relative to the scene in the absence of said optical deflection module.
3. The system of claim 1 , wherein said at least one camera is located along said first optical path to provide line of sight substantially similar to line of sight of the corresponding user's eye.
4. The system of claim 1 , wherein said eye display unit is configured to provide a desired field of view to be collected by said at least one camera unit.
5. The system of claim 1 , wherein said eye display unit comprises at least one lens located in said first optical path between the scene and said 95% or more reflective side of the double sided light reflecting optical element.
6. The system of claim 5 , wherein said eye display unit further comprises at least one additional lens located in said first optical path between said 95% or more reflective side of the double sided light reflecting optical element and said at least one camera unit.
7. The system of claim 6 , wherein the lenses located in said first optical path upstream and downstream of the 95% or more reflective side of the double sided light reflecting optical element form a telephoto lens system.
8. The system of claim 1 , wherein said at least one image forming module comprises an eye projection unit configured for projecting structured light indicative of one or more images onto the user's corresponding eye.
9. The system of claim 1 , wherein said at least one image forming module comprises an image display unit configured for providing displayed image data.
10. The system of claim 1 , further comprising first and second eye display units corresponding with right and left eyes of a user.
11. The system of claim 1 , wherein said eye display unit further comprises a control unit, said control unit is configured and operable for receiving image data collected by the at least one camera unit and generating corresponding display image data and transmitting said display image data to the at least one image forming module for providing corresponding imagery to the user.
12. The system of claim 1 , wherein said optical deflection module being configured to direct input light such that optical location and line of sight of the at least one camera unit corresponding with optical location and line of sight of the corresponding eye of the user.
13. The system of claim 1 , wherein said optical deflection unit provides that location of said at least one camera unit being at an eye equivalent location.
14. The system of claim 1 , wherein said at least one display unit being configured to provide seamless image display.
15. The system of claim 1 , wherein the optical deflection module comprises at least one reflecting surface configured to provide selected optical manipulation to light reflected therefrom.
16. The system of claim 15 , wherein said at least one reflecting surface is configured with at least one of the following: selected surface curvature, diffractive grating, and holographic element.
17. The system of claim 1 , wherein said at least one light deflecting module comprises at least one reflecting surface being flat.
